Have now got 6 flights on my SM Xtreme Hawk. What a great solid flier, especially with the Cortex gyro.
The first 2 flights were flown with a clean wing and resulted in major wing drops, but I then added the fences and VG's, plus added a little crow with the last 1/4 of full back stick. It has tamed the wing drop considerably and it is now very docile.
I added Unilights strobe and landing lights, scratch built a couple of the more prominent antennas and a pitot probe from Alan (Fiireblade5437). It really makes it stand out. I'm now waiting on some stencil decals from Tailormade.
I've used the settings from the manual, but then added crow with landing flap and almost double the landing flap deflection, probably close to 50mm compared to the suggested 30mm. It lands great. I had to replace the landing gear plywood mounts after the first couple of flights as they were extremely weak and they crumbled apart. They were easy to cut out and I used better quality plywood.
